Is anyone here familiar with the Android Sensor Simulator by OpenIntents?

To summarize my issue,I'm trying to get my App to detected when there is a change of light in the room. I can connect my app to the OpenIntents Sensor Simulator, but when I try to register a sensor Event Listener to the Sensor Manager, it fails.

I'm not home right now to run my code, and get the Stack Trace. I'll upload it soon.
